Abstract

The present description discloses systems and methods for changing the state of a device. One embodiment may include a device configured to provide a device in a first state, receive a signal indicative of first angular data of the device, and compare the first angular data to a first threshold. The device may then execute instructions to initiate a timer when the first angular data is greater than the first threshold, receive a signal indicative of a second angular data of the device, and compare the second angular data to a second threshold. When the second angular data is less than the second threshold and the time passed is within a pre-determined time period, the device may execute instructions to transition the device to a second state.

Claims

1. A method comprising:

providing a device in a first state;

receiving a signal indicative of first angular data of the device; and

when the first angular data is greater than a first threshold, causing the device to transition to a second state when a signal indicative of second angular data of the device is received prior to expiration of a time period and the second angular data is less than a second threshold, wherein the time period is based on receipt of the signal indicative of the first angular data of the device.

2. The method of claim 1, wherein the device comprises a wearable computing device.

3. The method of claim 1, further comprising executing instructions to initiate a timer when the first angular data is greater than the first threshold.

4. The method of claim 1, wherein in the first state an interface on the device is locked, and wherein transitioning the device to the second state comprises executing instructions to unlock the interface.

5. The method of claim 1, wherein the first state is a locked state, wherein the locked state comprises the device configured to detect an upward movement, wherein the upward movement comprises the first angular data.

6. The method of claim 1, wherein when the first angular data is greater than the first threshold, the method further comprises transitioning the device to a waiting for down state, wherein the waiting for down state comprises the device executing instructions to detect a downward movement.

7. The method of claim 6, wherein the first angular data comprises a first angular velocity, the second angular data comprises a second angular velocity, and wherein the downward movement comprises the second angular velocity.

8. The method of claim 1, further comprising:

applying a low-pass filter to remove angular data values that are above a pre-determined value.

9. The method of claim 1, further comprising:

determining that the device is stable prior to receiving the signal indicative of the first angular data.

10. The method of claim 1, further comprising:

causing the device to vibrate when the transition to the second state occurs.

11. The method of claim 1, further comprising:

causing the device to produce a sound when the transition to the second state occurs.

12. The method of claim 1, wherein the first angular data and the second angular data each comprise values indicating the position of the device relative to a reference point.

13. The method of claim 1, wherein the first angular data and the second angular data are each measured on an X-axis.

14. An article of manufacture including a tangible computer-readable media having computer-readable instructions encoded thereon, the instructions comprising:

providing a device in a first state;

receiving a signal indicative of first angular data of the device; and

when the first angular data is greater than a first threshold, causing the device to transition to a second state when a signal indicative of second angular data of the device is received prior to expiration of a time period and the second angular data is less than a second threshold, wherein the time period is based on receipt of the signal indicative of the first angular data of the device.

15. The article of manufacture of claim 14, wherein the article of manufacture is a heads up display device.

16. The article of manufacture of claim 14, wherein the instructions further comprise instructions to turn an interface on the device on when transitioning the device to the second state.

17. The article of manufacture of claim 14, wherein the instructions further comprise instructions to determine that the device is stable prior to receiving the signal indicative of the first angular data.

18. The article of manufacture of claim 14, wherein in the first state an interface of the device is locked, and wherein transitioning the device to the second state comprises executing instructions to unlock the interface.

19. A system comprising:

a processor;

at least one sensor;

data storage; and

machine language instructions stored on the data storage executable by the processor to perform functions including;

providing a device in a first state;

receiving a signal indicative of first angular data of the device; and

when the first angular data is greater than a first threshold, causing the device to transition to a second state when a signal indicative of second angular data of the device is received prior to expiration of a time period and the second angular data is less than a second threshold, wherein the time period is based on receipt of the signal indicative of the first angular data of the device.

20. The system of claim 19, wherein in the first state an interface of the device is locked, and wherein transitioning the device to the second state comprises executing instructions to unlock the interface.
